HYDROCA RBON MOTOR;

APPLICATION FILED NOV. 20. l9l5.

Patented Dec. 3, 1918.

Jig-

contacts arranged 180 degrees apart, and adapted to be operatedxfrom cam faces mounted ona single shaft, the disturbance of the firing balance of the motor,which is usually caused by eccentricityof cams and looseness of bearings on which they are mounted, is reduced to a minimum, so that 'the various cylinders on alternate revoluengine;

tions fire in substantial synchronism.

These and other objects will appear from the following description taken in connec tion with the accompanying drawings showing a preferred form ofi this invention, and in which: Y

Figure 1 is a diagrammatic view illustrating the invention, as applied toan ignition system, as used with' an internal combustion mary coil 12 and secondary coil 13. 14 represents a resistance'coil interposed between the induction coil and the timer 15, which will be more particularly hereinafter described, as provided with a plurality of sets of contacts, which are adapted to open and c ose the circuit to the ground connection 16,-w'hich forms a return to the source of current 10. It will be noted that the usual condenser 17 may be arranged to bridge across the gap made by the contacts of the timer when the circuit is broken thereby. A distributer 18, of usual form, may be connected with the secondary coil 13 of the in- 'duction coil, as at 19.

Referring particularly to Figs. 2 and 3,

i 20 represents acasing in which a'shaft 21 may be suitably mounted in bearings 22 in a transverse plate 23, mounted on an inwardly extending shoulder or flange 24. 26 indicates an insulating ring of suitable material, such as fiber, on which may bemounted a pair. of conductor rings 27 and 27'. These;

conductor rings may be secured in position, as by the screws 28, the ring 27 being provided with "an upwardly extending lug 29, which is adapted to be .connected to the terminal 30, which is arranged in the insulating bushing 31, mounted in the, casing 20. It will be noted that the terminal 30 is adapted to be. secured in position by means of a shoulder 32 formed thereon, and a nut 33,

i 13, represented in the diagrammatic view, is

which may be threaded on the member 30. It will be noted that the induction coil 12,

adapted to be connected, as at 34, to a member 35, which is suitably mounted on terminal 30, and insulated therefrom, and. is pro-.

11 represents a manually operated vided with an inwardly extending lug 35, to which is electrically connected the resist ance coil 14, the other end of which is connected to a housing cap 36, which is in electrical connection with the member 30,".and

is held in'proper position, as by the nut 37. It .will be understood that the coil 14 is properly insulated'by the spool 38 i The ring 27 is in electrical contact with the conductor plate 27, and is provided with a plurality of lugs 39, 'in which may be mounted a threaded contact 40, which may be locked in adjusted position, as by the Insulated studs 42,.on each of nuts 41. which is pivotally mounted a switch 43, are

secured in position as, bynuts 44. Each of the switches 43 is provided with a spring 45, which is grounded on the casing v2O.

Each of the switches is provided with a contact point 46, adapted to be intermittently brought into electrical connection with the contact 40.

It will be noted that the shaft 21 has formed thereon, or suitably secured thereto,-

amany sided cam 47, which is provided with of which are adapted to simultaneously raise the insulated abutments 49, which are suitably arranged. in the switches 43, as by pins 50.

' It will be notedthat a conductor 51, which may lead to the condenser 17 has an electrical connection, as at 52, with the termi:

nal 30.

From the above description, the operation of this invention will be understood as follows: Assuming the switch "11 to be closed,

current will flow from thesource of supply 10 through the primary winding 12, resistance coil 14 to the two lugs 39, and assuming the switches to be closed, the current will be divided between the two, and through the switches 43, passing through their respective springs 45 to the grounded casing 30 and to the battery 10. When the shaft 21 is revolved so that the abutments 49 ride on a eight diametrically opposed ridges 48, a pair pair of ridges 48, the contacts 40 and 46 are broken, thereby building up a charge'to be absorbed by. the condenser 17, which will be discharged'upon the making of the next contact, and thereby energizing the secondary winding 13, from which the current is conducted to the various spark plugs 53 by the distributer 18, which may be driven as desired,ffrom the shaft 21. Of course it is understood that the'spark plugs 53 may be" grounded in the usual way.

It will be seen from the foregoing description that there has been provided a timei comprising a pair of sets of contacts arranged in parallel, each of which is designed and constructed to carry the ,entire current flowing through the primary circuit; however, in normal operation, a portion of the current is adapted to How through each of operated in synchronism.
